5/8" Hitch Lock - 2" Receiver - Barbell - BlackMake the tow vehicle and trailer more secure by keeping them locked up tight with a CURT hitch lock. Like a hitch pin and clip, a hitch lock is designed to be inserted into the fastener hole in the side of a receiver tube to hold a ball mount or hitch-mounted accessory in place. While a CURT hitch pin does offer sufficient strength for keeping a ball mount firmly attached, a CURT hitch lock goes one step further.CURT hitch locks allow users to lock the ball mount into the trailer hitch, deterring theft and preventing anyone from detaching a trailer from the ball mount and towing away from the property without permission. This CURT hitch lock features a barbell design and comes with a 5/8" pin diameter to fit a 2" receiver tube size (usable pin length is 2.850"; will not work with double-walled receiver tubes). CURT barbell hitch locks are comprised of a pin with two end caps and a round locking mechanism. This hitch lock is key-operated and activated with a simple 1/4-turn. Also, the hitch lock comes with a watertight dust cap to keep out the elements and prevent corrosion. For the ultimate in towing security, a hitch lock and coupler lock used together will provide security at both the vehicle-side and trailer-side of the towing setup. For a boat, ATV, or camper, keep the toys more secure with CURT hitch locks.Features:5/8" diameter pin fits 2" x 2" receiver tubesThe usable pin length is 2.850" (not compatible with double-walled receiver tubes)Protected by a durable black finishEasy-to-operate, 1/4-turn lock activationA watertight dust cap prevents internal corrosionIncludes two keys for added convenienceSpecifications:Finish: Semi-gloss black powder coatHub Warehouse: D25Material: Carbon steelPart Type: Hitch lockPin Diameter: 0.625 in.Receiver Tube Size: 2 in.Warranty: Limited lifetime warranty (one-year finish, one-year parts)
